Supercharts realtime

Hi...I was wondering if one of you guys who use Tradestation could help a lowly Supercharts user. I want to see the formula Tradestation uses for their MACD indicator. I can't see it because I don't have Powereditor. I have this...MACD(PRICE,FASTMA,SLOWMA),but the canned MACD also has an MACDMA which is what I want to know how to express for a custom indicator. Thanks
